MS Documentation sucks (or how I got my VM hostnames to be set automatically from kickstart)

I wanted to automate my linux VM deployment on my Hyper-V based lab infrastructure. One small flaw: while DHCP does automatically update DNS, it does not do too much when your VM is named "localhost". I wanted to make the fedora deployment completely automated... which it is after I wrote a kickstart, except you can't get into the new box because you can't find its IP address.
